Higgs boson production at $e^+ e^-$ colliders: a model independent approach.

We consider non-Standard Model physics effects using an effective lagrangian parameterization. We determine the operators whose effects are most significant and extract the sensitivity to the scale of new physics generated by the existing data. We then consider processes containing the Higgs particle in $e^+e^-$ colliders as a probe for new physics effects, and demonstrate their usefulness in this area.
